Title: Top-roll bearer arm for the drawing mechanisms of spinning machines
IPC: D01H5/56
Filed: 1971-04-19
Abstract: 1336222 Top rollers; mounting and loading SKF KUGELLAGERFABRIKEN GmbH 19 April 1971 [12 March 1970] 26950/71 Heading D1D A bearer arm 18 for the top rolls 34 of a drawing mechanism for spinning machinery is raised from the operative position shown to an inoperative position, in which the top rolls are separated from fixed bottom rolls 40, by a lever 16 pivoted at 14 to a support 10 and having a pivotal connection 50 with the bearer arm, the latter also having a pivotal connection 52 with an arcuate link 54 pivoted at 56 to the support 10. Thus, when the lever 16 is raised, the tendency for the point of contact between the. top and bottom rolls to move anticlockwise around the bottom rolls due to the pivotal mounting 26 of the top roll holders is compensated by displacement of the bearer arm. A "partial-loading" position of the bearer arm is determined by engagement of the pin 52 with a spring 72. In this position the two top rolls, of which only one is shown, nearer to the support 10 are separated from their bottom rolls but the top delivery roll (not shown) i.e. the one furthest from the support 10, remains in contact with its bottom roll, being lifted therefrom on further raising of the lever 16 to force the pin 52 past the spring 72 and allow locking pins 64 carried by springs 62 on either side of the bearer arm to drop into holes in the support 10. Relative movement between the pin 50 and a hole 82 in the bearer arm bends the springs 62 to release the pins 64 from the holes in the support 10 on commencement of the return movement of the lever 16.

Title: Improvements in and relating to electro-luminescent devices
Inventor: RANBY PETER WHITTEN
IPC: H05B33/12
Filed: 1959-08-06
Abstract: An electroluminescent device comprises a layer 12 of phosphor embedded in a ceramic material disposed between two electrodes 10, 13, at least one, 13, of which is transparent and means 19 for maintaining a D.C. potential difference between the electrodes, the nature of the phosphor and ceramic layer 12 and the magnitude of the D.C. potential being such that when the D.C. potential is applied between the electrodes the layer 12 emits substantially no light, but upon excitation of the layer by radiation, e.g. visible light to X-rays, or cathode rays 17 which causes it to emit light, it continues to emit light for a substantial time after the excitation has ceased while the potential difference is maintained.  The ceramic material includes vitreous materials such as the enamels and glazes described in Specifications 733,260, 773,997, 780,584, 815,720 and 815,721, and the layer 12 can comprise enamel glaze and phosphor in the ratio of 72 to 28 by weight.  A layer 11 of enamel is formed between the electrode <PICT:0966730/C4-C5/1> <PICT:0966730/C4-C5/2> <PICT:0966730/C4-C5/3> 10 and the layer 12.  The electrode 13, which can be a conducting firm formed from stannic chloride, can be reduced in area around its edges and a layer of clear glaze 16 applied to leave a contact area 15 uncovered.  The electrode 10 can be of iron, aluminium or conducting transparent glass.  The phosphor can be formed from ZnS with or without CdS, MnS and MgCl2.6H2O, NaCl or BaCl2.  In order to reduce the slight D.C. electroluminescent effect of the phosphor gold can be added in the proportion by weight up to 0.1%, preferably between 0.0001 and 0.01%.  In the arrangement shown in Fig. 2 the excitation of the device is by radiation from a photo-flash bulb or X-ray device passing through a photographic negative 18 which is then removed. Fig. 3 shows a switching device in which the device 21 of Fig. 1 is arranged with its transparent electrode 13 facing a photo-conductive device 22 which can incorporate cadmium sulphide and is connected to an A.C. source 23, operation being caused by a flash of light or cathode-rays 24 entering the space between the devices 21 and 22.

Patent GB-273290-A (GB)
IPC: B65H63/00
Abstract: 273,290. British Thomson-Houston Co., Ltd., (Assignees of Adams, L. V.). .June 25, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Varnishes. - Resinous materials capable of being rendered infusible by heat, such as the condensation product of a polyhydric alcohol and a polybasic acid, of phenols and aldehydes, or the resin produced by the interaction of shellac and tannic acid are blended with a non-resinous ester of the aliphatic series, by heating these materials, preferably in the presence of a high boiling point liquid dispersing agent, which may or mav not be subsequently removed, to make varnish bases, &c. The esters generally employed are oils, those specified being linseed, perilla, soya, blown fish, castor, olive, rape seed, and cotton seed oils. Dispersing agents include benzyl benzoate, benzyl acetate, nitro benzene, toluidine, benzyl alcohol, cresol, resin, aniline, cumaron, diphenyl, glycol diacetate, phenyl-hydrazine, o-cresyl benzoate, having boiling points of 175-325 C. In an example, the condensation product of glycerine and phthalic acid (glyptal) is incorporated in any proportion, preferably equal, with china wood oil, by heating in the presence of benzyl benzoate to about 200 C. The glyptal is preferably used in its fusible state, although the product may be used in its infusible state, or the condensation may take place simultaneously with the incorporation of the oil. After removal of the high boiling point liquid, the mass may be dissolved in benzol, acetone, solvent naphtha, or the like, to form a varnish. Degelled oil, for example linseed oil which has been heated to 300 until it has thickened, and then, under continued heating, become liquid again, may be employed in the process, no dispersing medium being required in this case. The use of a dispersing medium may be dispensed with, decomposition products of the reaction serving the same purpose. Natural resins such as kauri may be blended with oils by the same process. Specification 235,595 is referred to.

Title: Improvements in or relating to the gasification of solid carbonaceous materials
IPC: C10J3/46
Filed: 1950-05-11
Abstract: 719,519. Gasifying solid carbonaceous materials. STANDARD OIL DEVELOPMENT CO. May 11, 1950 [Dec. 24, 1949], No. 27345/52. Divided out of 719,453: Class 55 (1)  In a fluidized process for gasifying particulate solid carbonaceous materials the entrainment of solids from the gasification zone, is reduced by continuously collecting the solids of less than 40 microns particle size entrained in the gases leaving the gasification zone and subjecting the fines so obtained to a treatment to reduce the' average carbon content thereof by at least 25 per cent by weight, the fines of reduced carbon content being returned to the gasification zone. The treatment to reduce the carbon content of the fines may comprise combustion or a secondary gasification. In the system shown in Fig. 1 entrained fines from a gasification zone 10 are separated in a separator 20 and pass by line 24 to a suspended phase burner 30. Oxygen and steam are fed to the burner through lines 34 and 38 and 40, a temperature of 2500‹-3000‹ F. being obtained in the burner 30. Hot gases containing oxygen and steam and low carbon content solids pass by line 12 to the gasification zone 10 to supply at least part of the heat required for the process. Additional oxygen and steam may be supplied through line 14 and solids from the zone 10 may  be circulated by lines 44, 50 and 14 combustion; of circulated solids occurring in line 14. Excess solids are withdrawn from the zone by line 44 through valve 46. Fresh solids are added to the zone by line 1 and a temperature of 1800‹-1900‹ F. and an operating pressure of about 400-500 lbs. per sq. in are maintained in the zone. In a modification heat is supplied to the gasification zone by circulating heated solids from a separate - fluidized combustion zone. Entrained fines are collected from both the gasification and the combustion zone and undergo combustion in a sus-. pended phase burner and are then returned to the combustion zone. In a further modification the collected entrained fines from the gasification zone are gasified in a secondary fluidized gasification zone. Solids entrained from the secondary gasification zone are at least in part passed to a suspended phase burner, combusted to reduce their carbon content and then returned to the primary gasification zone and/or secondary gasification zone. Fines of reduced carbon content may be returned directly to the primary gasification zone from the secondary gasificationzone. Specification 621,512 is referred to.
